FFXIV outdated patch cycle is one of the biggest issues in terms of content cadence.

Wasting dev time on older trust dungeons was by far the dumbest thing ever put into this game. You will have new players going through ARR and then get slammed with either crystal tower or 8 man trails. They have zero clue what the playerbase is actually like in instanced content, incredibly stupid design decisions I said when it came out.

This is all apart of their 10 year plan, to make sure that people can play the game when little to no one is around. All group content will eventually be trusts save for the raids.
